ARTHUR TREVOR DAWSON AND GEORGE THOMAS BlJ'CKHAM, OF WESTMINSTER, LONDON, ENGLAND, ASSIGNORS TO VICKERS LIMITED, OF WESTMINSTER,

ENGLAND.

Application filed October 14, 1915.

To all whom it may concern:

Be it known that we, Sir ARTHUR TREVOR Dawson, Knight, and GEORGE THOMAS BUCKHAM, both subjects of the King of Great Britain, residing at Vickers House, Broadway, Westminster, in the county of London, England, have invented certain new and useful Improvements in or Relating to Mountings for Automatic Guns, of which the following is a specification.

This invention relates to cycle side cars of the kind adapted to carry automatic guns.

1 According to this invention we provide means whereby an automatic gun together with its tripod mounting is detachably connected in its firing position on the side car frame in such manner that the gun and its mounting can be readily removed bodily from the side car when desired and used in the ordinary manner with the mounting resting on the ground. The gun is preferably carried by the side car frame in such a position that its muzzle projects in a forward direction and the side car may have a seat for the gunner so that the gun can be fired without his having to leave the seat. The forward portion of the side car frame preferably carries a horizontal bed plate or support of approximately triangular forma tion. This bed plate may have at or near its corners three curved seatings adapted to receive correspondingly shaped portions of the mounting. The rearmost seating may receive the lug, on the rear portion of the mounting, to which the forward end of the rear leg or trail of the tripod is pivoted. The other two seatings may. receive the machined portions of the pivoted ends of the front tripod legs. With the upper parts of these machined portions quick-release catches carried by the bed plate are adapted to engage in order to secure the gun and its mounting firmly in place.

Figure 1 is a side elevation showing more or less diagrammatically an automatic gun and its tripod mounting attached to the frame of a side car.

Fig. 2 is a plan of Fig. 1 but with the gun, its tripod mounting, and the aforesaid quick-release catches removed.

Fig. 3 is a side elevation of the aforesaid bed plate and the quick-release catches together with part of the tripod mounting, this View showing the bed plate reversed as Specification of Letters Patent.

compared with Fig. 1, that is to say the rear part of the bed plate is at the left hand portion of the View instead of at the right hand.

Fig. 4 is a'plan of Fig. 3, and

Fig. 5 is a side elevation of the front part of the bed plate as viewed in the di rection of the arrow in Fig. 4.

A is the side car frame, and B is the gun. B, B B are respectively the two front legs and the rear leg or trail of the tripod mounting. b, I) represent the aforesaid machined portions of the pivoted ends of the front legs and 6 represents the lug to which the forked end of the rear legor trail is pivoted. C represents the aforesaid bed plate and c, 0, 0 represent the curved seatings thereon for the reception of the parts 6'', b, 6 D, D represent the aforesaid quick-release catches. E represents the gunners seat.

In the example shown each of the aforesaid quick-release catches D, D, comprises a lever D pivoted at d to the seating 0' or to a bracket on the bed plate C. One arm of this lever is curved to bear against the upper surface of the machined portion 7) of the pivoted end of the front leg 13' and a suitable cushion or lining of leather or other suitable material may be carried by this curved arm. The other arm of this piece or arm D This arrangement is such that by depressing the fingerpiece or arm D until the link D passes from one side to the other of the pivot d of the fingerpiece or arm (-2. e., until the parts pass over their dead center) the pivoted lever D will be firmly held in its clamping position.

In placing the gun and mounting in position on the side car frame the front legs of the tripod are first folded against the rear leg or trail as shown in Fig. l, straps being used if necessary to keep them in this position. The spade B of the rear leg is caused to engage with a suitable abutment on a transverse member 6 of the side car framing and the mounting is then lowered on to the aforesaid seatings. The quick-release catches D, D are then moved to the operatiye position and the gun is ready, to be firedwhen inithis position. In .Order, to detach the n'xou'nting to enable the tripod to be placed on the ground the above stated operations are reversed.
